Definitions

  • the invention relates to a bearing comprising two hollow cylindrical support rings coaxially enclosing an imaginary axis, which are connected radially elastically by a bellows element made of elastomeric material, the bellows element having a profile with at least one fold projecting in the axial direction with an axial extension which does not overlap axial expansion of any of the support rings, at least one stop buffer being provided outside the axial extent of the fold, the stop buffer having a profile which, during intended use, extends radially in the direction of the other support ring from at least one of the support rings and that the stop partially overlaps with the fold in the radial direction.
  • Such a bearing is known from DE-A-1 575 727.
  • the bearing is provided for the vibration isolation of rotating shafts, in particular for laundry centrifuges, the bellows element being made thin-walled and having a wave-shaped cross section.
  • the wave crests and the wave valleys lie on concentric circles around the axis.
  • the flank parts of the bellows element have thickenings which are arranged in the circumferential direction and come to bear on the opposite part of the undulating cross section in the event of radial deformation.
  • the thickenings on the end faces of the bellows element are arranged in the axial direction outside of one of the support rings.
  • Another bearing is known from DE-GM 81 00 855. After that is an annular element made of resilient material. which is arranged directly between the outer surface of an inner ring and the inner surface of an outer ring.
  • the annular element made of elastic material is loaded unevenly by compressive and shear stresses, particularly in the case of large loads in the radial direction in the region of its folds projecting in the axial direction.
  • the buffering effect of the buffer which is designed as a wedge and is arranged in the elastically flexible material of the element, is unsatisfactory. Due to the wedge-shaped design of the buffer, the material is loaded unevenly and, in the event of large deflection movements in the radial direction, the surfaces which delimit the recess lie against one another, which greatly limits the service life due to the formation of cracks in the circumferential direction as a result of shear stresses occurring.
  • the invention has for its object to further develop such a bearing such that there is an increase in service life with better functioning of the bearing.
  • the bellows element consists of a thermoplastic elastomer material and that the stop buffer, viewed in the axial direction, is arranged within the support rings. Executing the bellows element from thermoplastic elastomer material is particularly advantageous in economic terms because of the simple, problem-free manufacture of the parts.
  • the maximum deflection of the bearing in the radial direction can be set precisely by the length of the stop buffers.
  • the bellows material has two folds which project in opposite directions in the axial direction, which are arranged on mutually different axial planes with respect to the imaginary axis and are formed integrally into one another in the radial direction are.
  • the design requires a large radial mobility of the bearing and extremely low loads in the event of radial deflection movements on the bellows element and the folds arranged within the bellows element.
  • a bearing designed in this way has consistently good usage properties over a long period of use.
  • the stop buffers can be ring-shaped.
  • this configuration requires a comparatively lower surface pressure of the stop buffers, as a result of which the specific material load is reduced and the service life is increased.
  • An axial stop can be formed on the radial stop.
  • the bellows element can be provided at the diagonally opposite corners of its profile with stop buffers projecting in the opposite direction. This arrangement of the stop buffers ensures uniform loading of the sealing bellows with maximum deflection of the bearing in the radial direction. In addition, no bending moments occur on the part enclosed by the bearing.
  • the stop buffers can consist of elastomeric material and can be formed in one piece with the bellows element.
  • the advantage here is that such a design in terms of manufacturing technology is of advantage and must be emphasized.
  • impact buffers made of elastomeric material reliably prevent impact noises in the event of extreme deflections of the bearing.
  • the stop buffers are formed by stop plates which are arranged in the area of at least one of the support rings.
  • differently designed stop buffers can be produced comparatively simply and subsequently assigned to the bearing.
  • the stop buffers are designed as radial and axial stops, such an embodiment has advantages, since both the stop buffers themselves and the bellows element used can be manufactured simply and separately in terms of production technology.
  • the bellows element is stiffened in the area of at least one support ring by a metal insert.
  • the metal insert can be provided with openings and can be penetrated with the bellows element in the region of the openings.
  • the metal insert requires greater stability of the comparatively soft bellows element on the outer circumference.
  • This metal insert also makes it possible to install the bearing directly in a circular opening in a housing without damaging the thermoplastic elastomer material.
  • the perforations in the metal insert, which are penetrated by the bellows element, ensure that the bellows element is fixed to the metal insert in a flawless and simple manner.
  • the components of the bellows element penetrating the perforations can be designed to merge into one another in the region of the rear side of the perforations. It is advantageous here that the fastening element of the bearing, for example in the form of a foot, is also made of the inexpensive thermoplastic elastomer material and can be integrally molded onto the bellows element in one piece.
  • a thermoplastic elastomer material is used and that at least one of the support rings in the region of its end projecting in the axial direction is thermally softened again after the shaping and hardening, reshaped in the direction of the other support ring and hardened by cooling becomes.
  • This method enables the bearing to be manufactured easily.
  • the stops are first integrally formed on the support rings of the bellows element in the axial direction. After removal from the mold, the stops are heated again and deformed in the desired direction.
  • a bearing is shown in FIG. 1, comprising two hollow cylindrical support rings 1, 2 coaxially surrounding an imaginary axis 7, which are connected radially elastically by a bellows element 3 made of thermoplastic elastomer material.
  • the bellows element 3 has two folds 3.1, 3.2 protruding in the axial direction and stop buffers 5, 6 which are provided to limit radial deflection of the bearing.
  • the stop buffers 5, 6, which assume the position shown in dashed lines after the bearing has been removed from the mold, extend substantially perpendicular to the imaginary axis 7 after renewed heating and subsequent deformation Material accumulations and high weight of the warehouse can be avoided.
  • the stops 5, 6 protect the folds 3.1, 3.2 of the bellows element 3 from damage and mechanical overload when there are large deflections of the bearing in the radial direction.
  • the second support element 2 is formed by a cranked metal ring which has openings 4 which are penetrated by the bellows element 3. A good, resistant and permanent fixation of the bellows element 3 on the support ring 2 and storage in a housing that surrounds the outside of the bearing is possible without any problems.
  • Figure 2 shows the bearing shown in Figure 1 in a view.
  • the fastening foot 10 which is provided for fastening the bearing, consists of metal and on the metal insert of the support ring 2 is attached.
  • a similar design of the fastening is also possible and is particularly advantageous for bearings which are less heavily loaded if the fastening foot 10 is molded directly onto the thermoelastic material of the bellows element 3 in the region of the support ring 2. Because of a clearer representation, the stop 5 is shown in the state directly after the demolding and before the shaping in the radial direction.
  • the bearings shown in FIGS. 1 and 2 can be used, for example, for mounting a cardan shaft.
  • FIG. 3 shows a further exemplary embodiment of a bearing of the type according to the invention, in which the stop buffer 6 is designed as a radial stop and is made of sheet metal, an axial stop 11 being formed on the radial stop in order to limit deflection movements of the support rings 1, 2 in the axial direction .
  • the stop buffer 6 is designed as a radial stop and is made of sheet metal, an axial stop 11 being formed on the radial stop in order to limit deflection movements of the support rings 1, 2 in the axial direction .
  • a further stop 12 projecting outward in the radial direction, which stops on a schematically illustrated component.
  • a circumferential, resilient bead 13 is arranged, which is made of elastomeric material and is formed in one piece with the bellows element 3.
  • the path limitation can have a progressive force-displacement characteristic, for example.
